SPECIFICATION formingpart of Letters Patent No. 650,253, dated May 22, 1900.

Application filed November 23, 1899. Serial No. 738,036. (No model) To all wh07n it may concern:

Be it known that I, HENRY KELLER, a citi-' zen of the United States, residing at Sank Centre, in the county of Stearns and State of Minnesota, have invented certain new and useful Improvements in Thrcshers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to threshing machinery, and most especially to threshers, the objects beingto improve the general construction of either the overshot or the undershot type; to provide in a single organized struc ture and mounted upon one truck a motorand threshing mechanism; to dispose the threshing and motor mechanisms upon the truckin sucha manner as to avoid interference and admit of any desired machinery replacing the threshing mechanism, whereby the truck and engine can be used for a variety of purposes; to equalize the strain upon both sides of the machine as nearly as practicable by providing two drive-belts; to obtain a maxim um amount of belt-surface, which is of material advantage, without necessitating the provision of an extra-heavy wide belt; to obviate the use of the ordinary steamengine and the dangers and risks incurred by its use; to dispose the parts compactly and facilitate the performance of the work in a rapid and efiective manner, and to devise a machine which will run smoothly and accomplish the required work in a thorough and effective manner.

I To those skilled in the art many ad vantages other than those enumerated will readily suggest themselves, and to this end and to a full disclosure of the invention reference is to be had to the following description and tl1e accompanying drawings, in which- Figure 1 is a perspective view of a machine constructed in accordance with and embodying the essence of the invention. Fig. 2 is a side elevation. Fig. 3 is a longitudinal section on the line X X of Fig. 4 looking in the direction of the arrows. Fig. 4 is a top plan view of the truck, showing the engine and belt-tightener in position. Fig. 5 is a detail longitudinal section of the front portion of a thresher of the undershot type, showing the application of the invention. Fig. (3 is a view similar to Fig. 5, showing the invention applied to a thresher of the overshot class. Fig. 7 is a detail view of the engine-housing. Fig. 8 is a detail view of the belt-tightener. Fig. 9 is a detail view of the truck. Fig. 10 is a longitudinal section showing the body of the truck mounted upon the axles and a fanblower arranged to deliver ajblast of air upon opposite ends of the cylinder. Fig. 11 is a detail perspective view of the front portion of a thresher, showing a different arrangement of the parts.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the sam reference characters.

It is contemplated to apply the invention to any style, make, or design of thresher or separator, whether of the overshot or the undershot type and whether the body of the truck is suspended from or mounted upon the axles, and the engine may be of any style not requiring a fire or boiler, preferably a gasolene or like explosive variety of engine,whereby casualties from fire are reduced to a minimum. It is therefore to be understood that in adapting the invention to meet the many conditions various changes in the form, proportion, and minor details of construction may be resorted to without departing from or sacrificing any of the advantages of the invention.

The truck A may be high or low, according to the style of Inachinet. 6., its body maybe suspended from the axles or'mounted there on. The low truck can pass over smooth roads, enables the use of front wheels of large diameter, and avoids a high lift of the bundies when feeding them to the thresher. If the fly-wheels of the engine are of large diameter or the machine is required to be drawn over rough roads and swampy lands, it is essential that the truck be highz'. e., that the body be mounted upon the axles, so as to provide ample room below the axles and truckbody for the clearance of projecting parts in the path of the machine. The body of the truck is composed of a cross-bar 1, rear axle 2, and a series of longitudinal timbers secured to the bar 1 and axle 2 and designated as side sills 3 and intermediate sills 4 4.

The front. axle .5 has the ordinary kingrbolt and fifth-wheel connection with thecross-bar 1 either above or below, according to the relative'position of the truck-body.

The engineB is mounted 'onthe intermediate sills 4 and the thresher and separator C on the side sills 3. It will thus beseen that the parts are independently mounted and 8, crank-arms 9 at the ends ofthe shaft 8, a-nd pulleyslO, mounted upon the crank-arms and capacity'of the machine.

that the thresher can be removed from the truck and readily substituted by other machinery to be driven by the engine.

The thresher and separator, either of the" overshot or the undershot type, is mounted upon the side sills 3 in any manner so as'to be removed, as shown in Figs. 3 and 4, when it is required to press the engine into service for driving other machinery.

The engi-neBflisof the type operated by gasolene, which is vaporized and mixed with air and: exploded, and is located at the front end of the machine,.below the threshing-cylinder,-

and will'be of any power, according to the size The crankshaft 6, operated from the engine, is belted to the thresher, two belts 7 being employed, j

as thereby a great amount of belt-surface can be obtained: to secure a positive transmissionof power. These drive-belts 7 are disposed upon opposite sides of the machine, with'a belt-tightener D, intermediateof theengine F and threshing mechanism, tightening the two i belts from one side of themaohine at thesame time. Thisbelt-tightener consists of a shaft and adapted'to bear against parts of the belts.

. A lever 11 is formed with or applied to one of the crankarms and is provided with the usual hand-latch 13 to cooperate with the teeth-of the'segment I2 and hold thetightener in an adjusted position.

- The engine is housed, the housing E being i 'li ned with: rubber or fine cloth 14 or other suitable material to make a tight closure. Access is had to the interior of this housing by means of doors, which are locked to prevent tampering with the engine'when left unattended or when it is required to keep un authorized parties from fingering the inclosed parts. Combined with the housing E is a suc tion-fan 15, attached to the rear end, which will continuously suck the dust, straw, and

all" dirtaway from the engine and blow it to one sidieof the machine or into the fanningmill of the separator to supplement theaction of itsfan. The housing E may be any neat cabinet-work and of a size and shape to in-- Q ,close-theengine without 10st space.

' The engine being of the explosive type its cylinderishea'ted when the engine is running, 1 the-overheating being prevented in the usual manner by circulating water through the jacket'fittedto the cylinder. The cooling is v also effected. bymeans of afan=blower 16,

.mounted upon a convenient portion of the machine-frame and having branch pipes 17 andlS extending therefrom andrunn'ing to opposite ends of the engine-cylinder, so as to deliver a blast of air thereon and keep it cool. These air-blasts also" serve to keep the interior of the housing E free from all dust and foreign matter.

The reservoir F for the gasolene or other volatile hydrocarbon may be located at the ;most convenient point, sons to be out of the 5 way and occupy the most advantageous posi* The'same is true of the barrel or tank T H for the water and the box G, containing the 5 battery for starting the engine-z .e., exploding the preliminary charges.

i barrel or tank H is placed either upon a platform 20 at the front end of the machine or upona shelf'2t at one sideof thethresh-er.

The feeders platform-21 is loca ted in front fof the platform 20 and is braced at its" outer iend-by means of chains 22, extending to the f-outer end of the' feed-table 23.

From the forgoing it will be readil yunder- Estood that the machine when completed is i compact in every part, is portable, and does not require the" employment of a steam-en- ;gi'ne for running the operating parts of the thresh'er and separating machinery;

Having thus described the invention, what @isclaimed as new, and desired tobe secured gby Letters Patent, is-

Lln threshing machinery, a truck comprising independent outer and intermediate longitudinal timbers, a separator mounted f upon the outer timbers, and an engineof the 5 gasolene type placed upon the intermediate timbers and disconnected from th'e'other tim bersand' the separator, substantially as and for the purpose described.

2. In threshing machinery, a truck, a sepa- 'rator and a gas-engine su pported'; thereon independently of each other upon independent timbers of the truck, with the engine beneath the threshing mechanism, and a l ined housing for said engine supported on the sam itruck-timbers, as set forth.

3. Inthreshing machinery, a truck, a separator and a gas-engine supported thereon on 1 independent timbers andindependent of each a other, withthe engine beneath the threshing mechanism, a lined housing for said engine fsupported' upon the same timbers therewith, and means-forkeeping said housing freefrom dust, substantially as specified.

In testimony whereof Iaflix my signature :in presence of two witnesses.
